Thermal conductivity of color-flavor locked quark matter

Understand

We compute the thermal conductivity of color-flavor locked (CFL) quark matter.

• At temperatures below the scale set by the gap in the quark spectrum, transport properties are determined by collective modes.
• In this work we focus on the contribution from the lightest modes, the superfluid phonon and the massive neutral kaon.
• The calculation is done in the framework of kinetic theory, using variational solutions of the linearized Boltzmann equation.
